Document Type and Number:
WIPO Patent Application WO/2017/199669
Kind Code:
A1
Abstract:
Provided is an underwater moving vehicle with which maneuverability of the vehicle can be improved and the position of the vehicle can be stably maintained. [Solution] This underwater moving vehicle is provided with a vehicle main body (1) of which the weight is set in advance so as to be greater than buoyancy underwater, a thrust section (32) that generates upward thrust by driving a screw propeller (21), a drive adjustment section (50) that controls the water depth of the vehicle main body (1) to a prescribed position by adjusting the driving of the screw propeller (21) and generating upward thrust equivalent to the difference between gravity and buoyancy, and a water flow deflector (34) that moves the vehicle main body (1) horizontally by deflecting downward water flow caused by the screw propeller (21).
